Hamilton's peaks (Silverstone in particular) were the highest, but for relentless, consistent maximising of his car's potential it has to be Kubica. Alonso only looked like the great driver he is after the summer break, Massa further improved, took a couple of races to get used to loss of t/c, and Vettel passed every test with flying colours.
Edge of the seat until the final corner for the maximum stakes; it has to be Brazil. Monaco because of the thrilling way it all panned out and great performances from all three podium men. Silverstone for a mesmerising demonstration of greatness. All three races have rain in common.
